Areas

While classes represent large groupings of information, areas represent the information that

Product Name monitors. For example, switch temperature, one of the values tracked by Fabric

Watch, is an area within the class Environment.

The tables in this section describe all of the areas monitored by Fabric Watch, organized by their

associated classes.

Environment class areas

Table 2 lists and describes the Product Name areas in the Environment class.

NOTE

Event Manager (EM) now manages fan monitoring; switch status is calculated based on fan status

reported by EM. You can use the fanShow command to view the fan status.

Fabric class areas

Table 3 lists Product Name areas in the Fabric class and describes each area.

TABLE 2 Environment class areas

Area Description

Power Supply Monitors whether power supplies within the switch are on, off, present, absent, or faulty.

Product Name monitors power supplies to be sure that power is always available to a switch.

Temperature Refers to the ambient temperature inside the switch, in degrees Celsius. Temperature sensors

monitor the switch in case the temperature rises to levels at which damage to the switch might

occur.

TABLE 3 Fabric class areas

Area Description

Domain ID Changes Monitors forced domain ID changes. Forced domain ID changes occur when there is a

conflict of domain IDs in a single fabric and the principal switch has to assign another

domain ID to a switch.

Fabric Logins Activates when ports and devices initialize with the fabric.

Fabric Reconfiguration Tracks the number of reconfigurations of the fabric. Fabric reconfiguration occurs when:

• Two fabrics with the same domain ID are connected.

• Two fabrics are joined.

• An E_Port or VE_Port goes offline.

• A principal link segments from the fabric.

Loss of E_Port Tracks the number of times that an E_Port or VE_Port goes down. E_Ports and VE_Ports

go down each time you remove a cable or an SFP (where there are SFP failures or

transient errors).
